ROOF FL .ASHIN G.

Application filed December 26, 1925. Serial No. 77,846.

g This invention relates to roof flashings, adapted to maintain water-tight joints between a roof and a pipe, such as a ventilating pipe, projecting upwardlytherethrough.e

pipe will be broken away and leakage will occur. 7

The principal object of the present invention is to provide a roof flashing which will permit limited relative vertical movement between the roof and pipe without disturbing the joints between the flashing and the pipe .or between the flashing and the roof. This is accomplished by making the flashing of two telescopic sections, one permanently secured to the roof and the other permanently secured to the pipe, there being a limited longitudinal movement permitted between the telescopic sect-ions to allow for the settling of the roof.

Another object is to provide a roof flashing which is adapted for use with roofs of various inclinations, as well as pipes vary ing somewhat insize.

Another object is to provide a roof flashing in which the pipe engaging collar is adjustable'in diameter to fit pipes of different sizes, or .to permit the collar to be passed over enlargements or projections ofthe pipe when the pipes are being assembed.

Other objects and advantages of this invention will be apparent from the following detailed description of one approved form of the device.

. the shingles 2, for excluding water. As

indicated, a portion of the shingle covering 2 has been removed to disclose the base plate 3 of the roof flashing, which base plate will ordinarily be anchored between the roof 1 and the shingles 2. Obviously, any other type of roof covering might be used in lieu of the shingles. is formed of sheet metal, and preferably stamped integrally therefrom is a projecting tapered sleeve portion 4, terminating in a cylindrical portion 5. The sleeve portions 4. and 5 extend at an angle to the perpendicular from the plane of base plate 3, for reasons hereinafter specified. A cylindrical sleeve member 6 is cylindrical sleeve portion 5 by a crimping projecting flange 7, on the continuous tube formed by members 5 and 6. The cylindricalportion 6 is practically a continuation of the cylindrical portion 5, and might be made integral therewith, it being formed from a separate piece of metal simply for convenience of construction. An out-turned flange 8 is formed at the upper free end of tube 6. A second tubular sheet metal member 9 has an inner enclose the periphery minates at its lower flange 10 adapted to closely surround the tubular member 6 beneath the flange 8. Obviously, the telescopic tubular members 6 and 9 are capable of relative sliding movements longitudinally of the axis of the two tubular members, this relative movement being limited by the engagement of flange 10 with either of the flanges 7 or 8 on the in ner tube 6. The interlocking engagement of the sleeve portions 6 and 9, provided by the flanges 8 and 10, will prevent complete separation of these members, whereby handling and shippingof the flashing, as a unit, is facilitated. These interlocking flanges of flange 8, and teralso help to prohibit leakage into the flashing at this extensible joint.

A collar 11 of soft malleable metal, such as lead, is secured to the upper edge of cylindrical member 9 by being cast or otherwise vformed about an irregular flange 12 at the upper edge of the cylindrical memher. The collar 11 is of hollow conical form, and preferably tapers from a relatively thick lower edge, where it is secured to tube 9, to a relatively thin upper pipe engaging edge 13. The diameter of the opening in the upper edge 13 of the collar is substantially the same as that of the pipe The base 3;

secured to the end in an inturned operatic-n, thereby forming an outwardly.

diameter suiflcient to 14, and a tight joint is formed between the pipe and collar by calking the edge 13 against the pipe, soldering it thereto, or any other suitable means of connection.

Although the collar llmay be made in the form of a continuous ring, or annular member, it is preferably split longitudinally at one side along a diagonal line, as at 16, to provide overlapping end portions so that the diameter of the ring may be slightly varied while still maintaining a tight joint at the split. Any suitable means may be employed for holding the split ends of the ring adjustably in engagement with one another, for example, angle plates 15 may be secured to the ends of the ring or collar adjacent the split 16-, the angle plates 15 being connected by an adjustable screw bolt 17 By opening the split in the collar 11, itis possible to pass the collar over outstanding flanges or other projections on the pipe section '14, when the pipes arebeing assembled, and the adjustable diameter of the opening in the collar permits its use with different range.

As has been previously noted, the tapered sleeve portion 4; extends at an angle to the perpendicular from base plate 3, so that the axis a; (Fig. 2) of the tubular sleeve portions 6 and 9, will be at an angle to this perpendicular. It will also be observed that the diameters of the tubular sleeves 6 and 9 are considerably larger than the diameter of the pipe 14. The pipe 1 1 will ordinarily be positioned vertically, and the roof 1 will ordinarily be slanting at an angle to both the horizontal and the vertical, and the features noted just above are for the purpose of adapting this roof flashing to roofs of various inclinations. The narrow edge 13' of the collar 11 is rounded .so thatsome freedom ofmovement is permitted the pipe section 1 within the collar, and the axis of the pipe 1%: need not coincide with the axis ac of the tubes 6 and 9, but the pipe may be positioned at various. angles'with respect to this axis as indicated by the dotted lines a and b in Fig. 2. This feature adapts the flashing for use on roofs varying considerably in their inclinationto the horizontal. The split collar 11 (if this feature is added) permits a greater range of variation in the size of the pipe 14L with which the device may be used, and also facilitates the assembling of the flashing on a pipe having flanges or other outstanding projections.

hen thedevice is positioned for service, the base plate 3 is anchored to the roof 1, and the pipe 14 is positioned through the tubular sleeve portions and the collar 11, with the cylindrical members 6 and 9 tele-- scoped, so that flange 10 is against or adjacent to the lower flange 7 on tube 6. The upper edge 13 of collar 11 is then calked or sizesof pipe 14:, within a limited otherwise permanently secured against the pipe 14: to form a water-tight joint between these two members. If new the roof 1 should settle with respect to the pipe 14, carrying down with it the base plate 3 of the flashing, it will not break loose the oint bet-ween the collar 11 and the pipe 1 1, as happens with roof flashings of the ordinary type, but the tubular members 6 will simply slide down withintheupper tubular member 9 without disturbing this tubular member 9 and the collar 11 whichremains securely anchored to the pipe 14:. Of-course, vertical movements of the pipe 1 1 with relation to the roof 1, if such should take place, will also be permitted by virtue-of this telescopic connection between the two cylindrical portions of the roof fl'ashing.

The base plate 3, taperedsleeve: 4:. and cylindrical sleeve 6, might be made of several connected parts, or all of1one integral member, and the collar 11 maytake other forms than that here illustrated, without departing from the essential features of this invention, as described hereinabove, and specified in the claims appended hereto.
